Abstract
The utility model relates to an integral combined valve type dual-tube oil and gas recovery wellhead device which comprises a tubing head, a tubing hanger mounted in the tubing head, and a Christmas tree fixedly connected with the tubing head through bolts. The Christmas tree comprises an integral combined valve with a group of tubing channels, a side outlet is arranged on each tubing channel, a manual flat valve is mounted at a position, corresponding to the side outlet of the corresponding tubing channel, on the integral combined valve, and each manual flat valve is fixedly connected with a fixed type throttling valve with a welding neck flange mounted through bolts. The integral combined valve type dual-tube oil and gas recovery wellhead device has the advantages the structure is simple; the integral combined valve adopts the multiple tubing pipelines, so that simultaneous recovery of different oil layers can be realized, and oil production and operating efficiency are improved; a packer can pack casing-tubing annuluses and pressure among oil tubes at the different oil layers, so that safe production is guaranteed, processing is convenient, and production cost is lowered.
Description
Technical field
The utility model relates to a kind of oil recovery, gaseous control head, and the dual tubing oil recovery of especially a kind of entire combination valve formula, gaseous control head belong to the oil and gas exploitation equipment technical field.
Background technology
Oil recovery, gaseous control head are the visual plants of oil, natural gas extraction, existing oil recovery, gaseous control head are comprised of casing head, tubing head and production tree three parts usually, but splicing sleeve, oil pipe, in order to carry out oil, natural gas extraction, pass through in addition the pressure of production control well head, regulate the flow of well head, be used for the special industries such as acid fracturing, water filling, test.Understand according to the applicant, oil recovery, gas well mouth are generally single tube oil recovery, gas well mouth, exploit simultaneously for multiple zone, and single tube recovers the oil, not only production efficiency is low for the gas well mouth, and low pressure reservoir easily is subject to compacting and the interference of high pressure oil reservoir, is unfavorable for the raising of each reservoir productivity of full well and recovery ratio.In addition, at same oil reservoir, the multiple-tubing string post is carried out oil producing operation simultaneously, or when carrying out simultaneously oil producing operation and water filling operation, need to separately open oil well, so not only investment is large, and cost is high, and easier welding health.
The utility model content
The purpose of this utility model is: propose a kind of reasonable in designly, safe and reliable, can improve the dual tubing oil recovery of entire combination valve formula, the gaseous control head of oil production and operating efficiency.
In order to reach above purpose, entire combination valve formula of the present utility model dual tubing oil recovery, gaseous control head, comprise tubing head, be arranged on boll-weevil hanger and the production tree that is fixedly connected with tubing head by bolt in tubing head, its improvements are, described production tree comprises the entire combination valve with one group of oil pipe passage, be shaped with side outlet on described oil pipe passage, on described entire combination valve, manual flat valve is installed in corresponding oil pipe channel side exit, described manual flat valve by bolt with its on welding neck flange is housed the fixation type throttle valve be fixedly connected with.
It is that described entire combination valve has two oil pipe passages that the utility model further improves.
It is that three main valves are housed on described oil pipe passage that the utility model further improves.
It is that the upper end of described entire combination valve is provided with tree cap, has two passages that are connected with the oil pipe passage on described tree cap, and stop valve and pressure meter are housed on described passage that the utility model further improves.
The utility model further improves, and described boll-weevil hanger is two post boll-weevil hangers, and its two post is connected with two oil pipe passages respectively.
It is that the lower end of described tubing head is provided with sleeve pipe, is provided with one group of packer in described sleeve pipe that the utility model further improves.
The beneficial effects of the utility model are simple in structure, the entire combination valve adopts a plurality of oil pipe passages can realize that different oil reservoirs exploit simultaneously, oil production and operating efficiency have been improved, but and the pressure between packer packing sleeve oil pipe annular space and different oil reservoir oil pipe, guaranteed safety in production, separately easy to process, reduced cost of production.
Description of drawings
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is the structural representation of the utility model embodiment one.
The specific embodiment
Embodiment one
A kind of entire combination valve formula dual tubing oil recovery of the present embodiment, gaseous control head, its structure as shown in Figure 1, comprise tubing head 1, be arranged on boll-weevil hanger 2 and the production tree that is fixedly connected with tubing head 1 by bolt in tubing head 1, production tree comprises entire combination valve 3, manual flat valve 6, fixation type throttle valve 5, welding neck flange 4, tree cap 7, stop valve 8 and pressure meter 9.Wherein entire combination valve 3 has two oil pipe passages, three main valves are housed on each oil pipe passage, its side has a side outlet, on entire combination valve 3, two manual flat valves 6 are installed at corresponding each side outlet place, every manual flat valve 6 by bolt with its on welding neck flange 4 is housed fixation type throttle valve 5 be fixedly connected with; The upper end of entire combination valve 3 is provided with tree cap 7, has two passages that are connected with two oil pipe passages respectively on tree cap 7, and stop valve 8 and pressure meter 9 are housed on each passage.In addition, boll-weevil hanger 2 is two post boll-weevil hangers, and its two post is connected with two oil pipe passages respectively.
During use, the first oil pipe 10 and the second oil pipe 11 are installed respectively in two oil pipe passages of entire combination valve 3, when when two different oil reservoirs recover the oil simultaneously, one end of the first oil pipe 10 is connected with the first endowel of boll-weevil hanger 2, the other end puts in the first oil reservoir 12, one end of the second oil pipe 11 is connected with the second endowel of boll-weevil hanger 2, and the other end puts in the second oil reservoir 13.Interior the first packer 15 and the second packer 16 of arranging of sleeve pipe 14 in tubing head 1 lower end connection, but packing sleeve oil pipe annular space not only, but the pressure between packing the first oil reservoir 12 and the second oil reservoir 13 also, to avoid low pressure reservoir to be subject to the interference of high pressure oil reservoir, and then each oil reservoir of full well is developed fully, improved recovery ratio.
In addition to the implementation, the utility model also can have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, drop on the protection domain of the utility model requirement.
